Note on Four Dp-Branes at Angles

Abstract

In this note we analyse the dynamical potential of a system of four $Dp$-branes at arbitrary angles. The equilibrium configurations for various values of the relative angles and distances among branes are discussed. The known configurations of parallel branes and brane-antibranes are obtained at extrema of the dynamical potential.Comment: misprints corrected, a new paragraph added, 11 pages LATe
